Chromomagnetic dipole moments of light quarks in the Bestest Little Higgs Model

Abstract

In this paper, we research into the anomalous Chromomagnetic Dipole Moment (CMDM), denoted as ${\hat{\mu }}_q^{BLHM}$, of the light quarks $q=(u,c,d,s,b)$ within the framework of the Bestest Little Higgs Model (BLHM) as an extension of the Standard Model (SM). Our investigation encompasses novel interactions among the light quarks, the heavy quark $B$, and the heavy bosons $(W^{\prime \pm },H^{\pm },{\varphi }^{\pm },{\eta }^{\pm })$, incorporating the extended Cabibbo-Kobayashi-Maskawa (CKM) matrix characteristic of the BLHM. We thoroughly explore the permissible parameter space, yielding a spectrum of CMDM values ranging from $10^{-10}$ to $10^{-3}$.
